XHAILe

Explainable Hybrid AI for Computational Law and Accurate Legal Chatbots (XHAILe) aims to provide efficient and accurate hybrid AI technologies for computational law and natural language interaction with e-government solutions along with trustworthy benchmarks and guidelines for legal use of the technology.

The XHAILe Grand Solutions project brings together leading Danish researchers in law, language technology, AI and computational law and providers of digital public administration and legal tech software, to develop accurate and explainable Hybrid-AI solutions that combine efficient AI-based translation of law to an open computational law rule format and a conversational agent using a rule engine via an open API. Here come trustworthy, new legal benchmarks and guidelines for the use of the technology. The results will be evaluated and demonstrated on use cases from local and central government.
